HD 215152 is a star with 0.77 times the mass of the Sun, and 0.73 times its radius. It is located 70.44 light years away from the solar system.
HD 215152 is known to have 4 exoplanets in orbit around it.
HD 215152 b was discovered by the La Silla Observatory observatory, in 2018-06, using the radial velocity method. Its semi-major axis is 0.06 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of HD 215152 b is 1.819 times the mass of Earth. The radius of HD 215152 b is 1.190 that of Earth. At 1.819 Earth masses, HD 215152 b is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes. No Super Earths are known to exist in our solar system, but if it exists, the so-called Planet Nine could very well be a super Earth, as it is hypothesized to have a mass between five and ten Earth masses.
HD 215152 c was discovered by the La Silla Observatory observatory, in 2018-06, using the radial velocity method. Its semi-major axis is 0.07 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of HD 215152 c is 1.720 times the mass of Earth. The radius of HD 215152 c is 1.170 that of Earth. At 1.720 Earth masses, HD 215152 c is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes.

HD 215152 d was discovered by the La Silla Observatory observatory, in 2018-06, using the radial velocity method. Its semi-major axis is 0.09 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of HD 215152 d is 2.802 times the mass of Earth. The radius of HD 215152 d is 1.480 that of Earth. At 2.802 Earth masses, HD 215152 d is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes.

HD 215152 e was discovered by the La Silla Observatory observatory, in 2018-06, using the radial velocity method. Its semi-major axis is 0.15 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of HD 215152 e is 2.878 times the mass of Earth. The radius of HD 215152 e is 1.510 that of Earth. At 2.878 Earth masses, HD 215152 e is a so called Super Earth.
